Abstract

The present invention relates to a kind of absorbent commodity (1) such as sanitary napkin or incontinence pad, it has longitudinal lateral margin and lateral end edges and top layer (8), the bottom (9) of fluid impermeable and the absorbent cores (10) between the top layer (8) and bottom (9) including fluid penetrable.Absorbent cores (10) are included with the first absorbed layer (11) and the fluid flow control structure (13) between first absorbed layer (11) and the bottom (9) for extending through its opening (12).First absorbed layer (11) has longitudinal direction anterior (6) and longitudinal rear portion (7) and the narrow transverse changeover portion (14) between anterior (6) and the rear portion (7).The width of the narrow transverse changeover portion (14) is located in the front portion (6) of first absorbed layer (11) for the 20 50% of the longitudinal length of 50 75% and the opening (12) of the most wide transverse width of anterior (6) of first absorbed layer (11).

Description

Absorbent commodity
Technical field
The present invention relates to a kind of absorbent commodity such as sanitary napkin or incontinence protection, it, which includes having, extends through opening for its The absorbent cores of mouth.
Background technology
This kind of absorbent commodity being worn in general underpants includes absorbent napkin or the absorption that adult-incontinence or women are used Pad.
Absorbent napkin or absorption pad are usually provided with the absorbent cores for accommodating and keeping body fluid.In order that this absorbent commodity has Work to effect, the necessary Quick Acquisition body fluid of absorbent cores enters in structure and then by body fluid compartments from the viewpoint of application Suppressed with through absorbent cores with the seepage for providing maximum.When subsequent dirt is pointed to and dirt identical regional area before When, the opening of the collection/distribution layer and core that are connected in core is helpful, because the regional area tends to have been filled with coming from it The liquid of preceding dirt.
It is special because the type of these articles must be resized and be configured to fit in the confined space of crotch portion of undergarment It is that they may be leaked at lateral margin before all absorbabilities of article run out to determine problem.Fluid on the contrary will be in article Top layer on flowing cocurrent to outside lateral margin, seepage and the clothing of wearer may be polluted in this fluid.When fluid is outside top layer When being flowed in portion, additional disadvantage is that the major part of the top layer contacted with body will be moist.This is certainly very undesirable, Because it causes article unhealthy and undesirable for wearer.
The absorbent napkin and absorption pad that significant effort has had been made in the past to overcome to be used for incontinence or women are related Side leakage problem.
